  • EFFICIENCY IMPROVEMENT FOR POWER FACTOR CORRECTION BASED AC-DC POWER ADAPTERS
    Publication number: 20230402914
    Abstract: Controlling power factor correction (PFC) in a secondary-controlled alternating current (AC) to direct current (DC) (AC-DC) power adapter is described. In one embodiment, an apparatus includes a transformer, a primary-side controller coupled to the transformer, a PFC component coupled to the primary-side controller, and a secondary-side controller coupled to the transformer. The secondary-side controller is configured at least to obtain data informative of an amount of power, and control, based on the amount of power, a PFC operating mode of the PFC component.

  • PSEUDO-DIGITAL LIGHT EMITTING DIODE (LED) DIMMING WITH SECONDARY-SIDE CONTROLLER
    Publication number: 20210400789
    Abstract: Pseudo-digital light-emitting diode (LED) with secondary-side flyback control is described. In one embodiment, a Digital Addressable Lighting Interface (DALI) compatible driver includes a secondary-side controller coupled to a secondary winding of a transformer and coupled to a light-emitting element. The secondary-side controller includes a DALI-compatible interface to receive information. The secondary-side controller communicates a control signal with a primary-side controller via a galvanically-isolated link. The primary-side controller is coupled to a primary winding of the transformer. The DALI-compatible driver modifies a light output of the light-emitting element in response to the information.
